Trolley-way

MICHEL DILLENBURG, OF SAN FRANCISCO, CALIFORNIA.

TRO LLEY-WAY.

SPECIFICATION forming part of Letters Patent No. 572,874, dated December 8, 1896.

Application filed. April so, 1896. Serial No. 589,626- (No model.)

To all whom it may concern.-

Be it known that I, MICHEL DILLENBURG, a citizen of the United States, residing in the city and county of San Francisco, State of California, have invented certain new and useful Improvements in Trolley-Ways; and I hereby declare the following specification and the drawings therewith to be a complete description of my invention, its objects, and manner of constructing the same.

My invention relates to trolley-ways for conveying weights of any kind in factories, warehouses, or slaughter-houses, and especially to switches or transfer-points for such ways.

My invention consists in mounting the movable members or shifting rails by means of an elastic clamping-joint that will yield, so the switch rail or point can be swung in either direction and still remain in register with the fixed rail, of which the movable one isa continuation.

The objects of my invention are to avoid all lost motion in the movable joints and to cheapen and simplify their construction.

Referring to the drawings herewith, Figure 1 is a side view of a section of a trolley-way suspended from a ceiling. Fig. 2 is a plan view of the same, looking from the top, the hangers being shown in section. Fig. 3 is an enlarged view of the yielding joint that permits movement of the shifting point or rail. Fig. 4 is a plan view of mechanism for moving the hanger l3 and the switch-bar A Similar letters of reference indicate corresponding parts.

The rails or bars are set on edge and attached by rivets or bolts to the hangers B and B the former fixed to the ceiling or other suitable support and the latter sliding thereon by means of suitable mechanism, such as is shown in Fig. at. On these rails A A A A run trolley-wheels E, provided with pendants F and hooks E or other apparatus to receive loads of any kind to be transported.

To transfer from one line of rails to another line, as from A to A or A", as seen in Fig. 2, there is a swinging switch-bar A arranged to move in the are a a by any suitable means, usually a pulley G, that can be turned by a chain from the floor below, and a link 1, connecting from a crank-pin T to the hanger 13*, which slides on its base or supporting plate and moves with the movable rail A This movable rail A has its fulcrum or fixed point at its inner end J, Fig. 3, and is held to the hanger B by means of a bolt L, that passes through the rail A and hanger B, as shown by dotted lines, also through an elastic spring M, preferably of india-rubber, the whole being clamped by a nut N.

The face of the hanger B (shown in section) is beveled, as seen at 0, so the rail A can be swung to the position indicated by dotted line P or can swing the other way to the dotted line Q, being in all positions held firmly against the hanger B by reason of the elastic spring or collar M, and also is held in register with the rail A by reason of bearing at the fulcrum-point J against the hanger B.

The fixed rails A A A are held by throughbolts or rivets R in the usual manner.

It is obvious that the elastic pressure provided by the collar M can be attained by a coil-sprin g or other suitable device. I have shown only the most simple form of providing a spring.

It is obvious that movable joints of this kind can be applied at various points in a line and that two such joints can be provided on one hanger if the face of the hangers Bis beveled each way, as indicated at R in Fig. 3.

Having thus described the nature and obj ects of my invention, also the manner of constructing and applying the same, what I claim as new, and desire to secure by Letters Patent, is

1. In a trolley-way, the movable switch-bar A clamping-bolt L, spring M, the latter maintaining an elastic clamping strain when the bar A is moved for switching purposes, in the manner substantially as described.

2. In a trolley-way, the movable switch-bar A clamping-bolt L, spring M and hanger B, the latter curved or beveled on its front or bearing face to permit movement of the bar A in the manner and for the purposes substantially as described.

In testimony whereof I have hereunto affixed my signature in the presence of two witnesses.

MICHEL DILLENBURG.
